Imaging of Anti-Cancer Drug Uptake in Spheroids using DLS

Spheroid 3D cell culture models mimic the physiology and functions of living tissues making them a useful tool to study tumor morphology and screen anti-cancer drugs. The drug AZD2014 is a recognized…

透明介质对组织透明度和收缩的影响

本研究通过比较新鲜解剖的双翅目昆虫脑与其透明化处理后的等效物,全面评估了不同透明化介质对组织透明度和收缩率的影响。组织透明化处理结合光片显微技术,已成为全器官三维成像和定量的强大工具。由于组织透明化处理有助于在亚细胞水平上对完整组织进行光学成像,它有潜力揭示如大脑等复杂器官以前未见的细节。为了对厚样本进行高分辨率成像,透明化介质需要与高数值孔径(NA)物镜使用的浸没液具有匹配的高折射率。这一点对于…

Understanding Motor Sequence Generation Across Spatiotemporal Scales

We have developed a microscopy-based pipeline to characterize a developmentally critical behavior at the pupal stage of development, called the ecdysis sequence. We study brain-wide neuronal activity…

Confocal and Light Sheet Imaging with STELLARIS DLS

Optical imaging instrumentation can magnify tiny objects, zoom in on distant stars and reveal details that are invisible to the naked eye. But it notoriously suffers from an annoying problem: the…

应用的领域

类器官和3D细胞培养

生命科学研究中最令人振奋的最新进展之一是3D细胞培养系统的发展,例如类器官、球状体或器官芯片模型。 3D细胞培养物是一种人工环境,在这种环境中,细胞能够在三维空间中生长并与周围环境相互作用。 这些环境条件与它们在体内的情况相似。

模式生物研究

模式生物是研究人员用来研究特定生物学过程的物种。 它们具有与人类相似的遗传特征,通常用于遗传学、发育生物学和神经科学等研究领域。 选择模式生物的原因通常是它们在实验室环境中易于保持和繁殖、生成周期短,或能够产生突变体来研究某些性状或疾病。
